The object of the present invention is to; provide a novel, simple andeffective lath,

structure, which can be easily applied and which will require a minimumamount of. 5 plaster to produce a finished and effective.

section of the lath structure and plaster thereon. In the embodimentdisclosed a backing sheet, designated generally by the reference paperor similar material, is employed and these two sheets are securedtogether by an 1:

interposed layer or ply 9 of asphaltum or other Waterproof material. Thebacking sheet 5 as thus preferably constructed, is

stamped to form continuous longitudinal and transverse reinforcing ribs10 on its rear side. These ribs produce in the front facecorrespondingly shaped grooves or channels 11. The surface of therectangular portions defined by these channels and designated 12 issubstantially flat.

Over the face is laid a metallic lath structure, preferably consistingof right angularly disposed lath rods 13 and 14: that are welded orotherwise secured together at their points of intersection. These rodsare preferably spaced so that certain of the same intersect on the fiatsurfaces 12 and extend transversely across the channels or grooves 11.Others extend longitudinally along and over said grooves, beingsupported by the interposed rods that lie upon the flat surfaces 12.This metallic fabric is secured to the backing sheet by any suitablemeans, as staples 15 that preferably pass through the flat surfaces 12and embrace certain of the rods ad- -jacnt' their points of other. rods.

the spirit or sacrificing any of the advantages of the invention.

What we claim is:

1. A plaster supporting structure, comprising a backing sheet having agenerally flat face and spaced apart continuous pockets opening throughsaid face, lath rods extending along said face of the sheet, certain ofsaid rods being located longitudinally over the pockets between the sidewalls thereof and spaced from their bottoms, and means securing the rodsto the sheet.

2. A plaster supporting structure comprising a backing sheet having agenerally flat face and spaced apart continuous pockets opening throughsaid face, angularly disposed intersecting lath rods laid along saidface of the sheet, certain of said rods being located longitudinallyover the pockets between the side walls thereof and spaced from theirbottoms, and means securing the rods to the sheet.

3. A plaster supporting structure comprising a backing sheet havingrearwardly outstanding intersecting stifiening ribs forming intersectinggrooves that open through the face of the sheet, and a lath fabricoverlying the face of the sheet and secured thereto.

4. A plaster supporting structure 'f prising a backing sheet havingrearwardly outstanding intersecting stiffening ribs forming intersectinggrooves that open through the face of the sheet, and a lath fabricoverlying the face of the sheet and comprising intersecting rods securedto the sheet, I

certain of said rods extending longitudinally along the open sides ofthe grooves andcertain lying on the substantially fiat face of thebacking sheet and secured thereto. 7

6. A Wall structure including a backing sheet having lntersectingchannels in its front face, lath rods extending oversaid channels, and aplaster body over the front face of the backing sheet, said body havingthe lath rods embedded therein and filling the channels, therebyproviding intersecting stiffening ribs for the Wall structure.

In testimony whereof, We affix our signa-- tures;
